Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2522, here are decompositions:
- 19 + 2503 = 2522
- 139 + 2383 = 2522
- 151 + 2371 = 2522
- 181 + 2341 = 2522
- 211 + 2311 = 2522
- 229 + 2293 = 2522
- 241 + 2281 = 2522
- 271 + 2251 = 2522
Showing the first eight; more decompositions exist.

The digit sequence 2522 first appears in π at position 822 of the decimal expansion (the 822ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
